There are several reasons that you may want to gain weight quickly. It could be that you are underweight and your doctor thinks it is medically necessary for you to pack on the pounds. Athletes and bodybuilders may also desire to gain weight quickly. Although you can gain quickly, make sure you do it in a healthy manner to avoid any adverse medical conditions.
Step 1
Use a weight gain supplement. There are numerous protein shakes available that can pack in a lot of calories in each serving. As an example, GNC's Weight Gainer Gold has a massive 2,200 calories in each 24-oz serving.
Step 2
Up the number of calories you eat each day. Try to get at least 500 calories more a day. You'll need a total of 3,500 extra calories to gain one lb..
Step 3
Double your portion sizes. Eat larger portions and consume meals more frequently to gain weight quickly. Aim to have at least three to four hefty meals per day along with snacks.
Step 4
Add healthy fats to meals to pack on the pounds quickly. Use olive oil, canola oil, avocados, nuts and peanut butter liberally. These food items are all high in unsaturated fat.
Step 5
Drink high-calorie milk shakes, whole milk and fruit juice. Avoid soda and alcohol when putting on weight.
Step 6
Increase the intensity of your weight training routine. Adding muscle mass can help you put on weight quickly. Aim to increase the weight you use by five percent each week. Work a different body part each day and rest a day between routines.
